public class AutoRotation
extends javax.media.j3d.Interpolator

AutoRotation is a java3D Interpolator object used to continously rotate the scene graph.

 rotator = new AutoRotation(transformGroup);
 rotator.setSchedulingBounds(bounds);
 bg.addChild(rotator);
 

The above code will add the AutoRotation object to the branchgroup group.

Initializes the wake up event:wake up every 25 miliseconds

Overrides:

initialize in class javax.media.j3d.Interpolator

processStimulus

public void processStimulus(java.util.Enumeration e)

Rotates the scene graph with a small angle each time wakes up

Specified by:

processStimulus in class javax.media.j3d.Behavior

setRotParams

public void setRotParams(long duration,
                         double angleX,
                         double angleY)

Sets up the rotation parameters

Parameters:

duration - The time between mouse pressed and mouse released

angleX - During the mouse drag, how much angle has been rotated around the x axis

angleY - During the mouse drag, how much angle has been rotated around the y axis
